tus using gaseous fuelpfor the production of heat. I

The primary object of the present invention is to provide a heating apparatus which is adapted to use gaseous fuel in such a manner as to store, retain and radiate the heat in a more eflicient manner than has heretofore been obtained 7with the use of a conventional type of stove or the like.

' Another object of the present invention is to provide a means for a gas burner heating apparatus which is adapted to retain and maintain heating elements in predetermined positions and to concentrate and connelthe heat so as to forceit to travel in certain well defined paths and permit it to escape into the room or. enclosure containing the vheating apparatus.` a y A further object is to provide means for supporting the heating elements in such a manner as to hang them in predetermined positions with respect to each other and prorange the heating elements in such a manner as to providefor automatic mixture of air,

and gas under all pressures of gas to provide for proper combustion and thereby intensely heat the heating elements. i

These and other objects are attained by the conventional apparatus illustrated in the accompanying drawing in which:

.In the drawings the invention is shown.

applied to a gas burner heating apparatus the exterior of` which is shown conventional in form.

In the manufacture and construction of my invention a bottom plate 1 is provided and a closed back wall 2 is attached thereto through the medium of screws 3 or other well knownfastening means. A The bottom plate 1 is provided with upstanding lugs 4 to which the side walls 5 and 6 are attached by screws 7 or the like. An upstanding horizontal flange 8 is provided on the bottom plate 1 and a partition plate 9 attached thereto through the medi-um of rivets 1 0 or the like in spaced relation to the backwall 2 as shown in Fig. 2. The space between the back wall 2 and partition wall 9.ispreferabl filled with fire brick 11 or like material. llpstanding horizontal flanges 12 and 13 are formed on the bottom 1 and spaced apart to receive, retain and hold in position the side lire brick yWalls 14 `and 15 as shown in Fig. 1.

Front plates 16 and 17 are attached to the side walls 5 and 6 by screws 18 or the like as shown in Figs. l and 2.4 The faces of the plates 16 and 17 canr be provided with any desired design. The meeting ends of the side7 back, bottom and top walls are preferla hearth7 the larger portion of the pan eX- tending inwardly over the 'bottom 1 and maintaining the pan in its proper position, because the greater weight thereof is resting or being supported upon the bottom 1 of the heating apparatus.

Fire brick 23 or similar material lis laid in the pan as shown in Fig. 2 which can be of any design desired. rlhe entire heating apparatus is supported by conventional legs 24 or the like. rl`he top 25 of the heating apparatus can be made of any form but is preferably provided with ay curved downwardly extending portion 26 as shown in F igs. 1 and 2. A series of openings 27 are provided in the top portion 25 as shown in Figs. l and 3.

lin the preferred form as shown in Fig. 3 the members28 are provided on the downwardly projecting portion 26. The members 28 are dove-tailed to receive counterpart dove-tailed portions formed on the top portion of the heating element 29l and asbestos 30. The lower endsof the asbestos 30 and heating element 29 engage the channel formed by the spaced apart flanges 31 and 32 thereby holding same in a predetermined position. 1

It will be observed that a space 33 lis provided between the'bottom 1 of the heating apparatus and the ends of the asbestos and heating elements to provide for expansion and contraction when the heating element is subjected to heat from the burner. l

A series of cone shaped deflectors 34 are provided on the heating element 29 which serve to direct, diffuse, focus and radiate the heat from the burner. lt will be observed that the heating element 29 is not provided.

with openings or apertures and that the asbestos 30 prevents the heat from radiating into the chamber 35 thereby tending to force the heat toward the front heating element 36. The heating element 36 is attached to the heating apparatus `in the same manner as the heating-element 29 hereinbefore described. The heating element 36` is rovided with a series of heat delectors 37 which are arranged in staggered relation with respect to the heat delectors 34.

The heat delectors 34 and 37 project to,-

ward each other or in opposite directions as' shown in Fig. 3.

It will be observed that the heating ele? ments are spaced apart in such a manner as to leave a larger space 38 at the bottom than at the top 39. This .arrangement provides means of concentrating the heat within a smaller space just prior to its passage into the chamber 35 and out through the apertures 27 into the enclosure or room.

j, rlhe heating element 36 is provided with a series of openings 40 which vary in size from the bottom to the upper thereof.

A front plate 41 is attached to the depending portion 26 of the top 25 in the same manner as the heating elements and asbestos. It isi however, as shown spaced apart from the heating element 36 leaving a chamber 42.

|lFhe front plate 41 can be provided with any design desired such as shown at 43.

A burner 44' is interposed between the heating elements 29 and 36 and is provided with a series of jet openings extending substantially from side to side of the heating apparatus, as shown in Fig. 2. The fuel is supplied through a'pipe'45 which isregulated by a conventional type 'of valve 46.

An aperture 47 is provided in the heating element 36 to permit of the passage of heat through and into the aperture 48 formed in the heating element 29 and asbestos 30 whence it escapesthrough the apertures 27 formed in the top of the stove.

portion In order to provide protection for the part 26 of the downwardly projecting portion of the top 25 an apron member 49 is provided` and attached to the top portion so as to leave a space 50 between 4the downwardly dependingportion 26 and the apron .to allow a ycold draft of aii' tocool, the depending portion 26- of thetop and keep it yvided in the bottom portion lof the heating apparatus to permit a current of air to pass up through the chamber 35' and mix with the hot air from the passage thereby forcing the heat to escape out through the apertures v27 into the enclosure or room 'surrounding the heating apparatus.

'1t will also be observed that circular spaces 53 are provided aro-und the burner' jets to Ypermitof a free circulation around tween and over the heating element..

If desired a conductor flue 54 can be atf, tached to the heating apparatus and brought into communication with the chamber shown in Fig. 1. The modification shown in `7 is conv1'25 carryoff the byproducts ofcombustion*as*`I --L structed and designed similar to the pres ferred construction. hereinbefore described 12'0 the burner and up through thel space b e- 58 which is attached through the medium of lugs 59 to the side walls of the heating apparatus.

The modification shown in Fig. 8 -is similar to the preferred form of construction hereinbefore described except that the upper portions of the heating elements and asbestos are curved in reverse relation and attached to the partition wall 9 of the heating apparatus'as shown in Fig. 10.

Alined apertures 60, 6l and 62 are formed in the heating elements and asbestos permitting the heatto pass into the c-hamber 63 of Fig.8 and out'into the enclosure or room through apertures 64 as shown in Fig. 7.

In the modification shown in Fig. 7 no apertures are provided in the asbestos o1' heating elements as they are all spaced apart permitting the heat Ato escapeup into a chamber .65 and out into the room through aprrtures 64 formed in the top of the heating apparatus.

It will be observed that the modified form shown in Figs. 7 and 8 do not have an apron Such as shown at 49 to maintain the depending portion 26 cool through the medium of a cool dra-ft of air, but it will be obvious that the same can' beY usedif desired and found preferable. i`

The operation fof` the'heating apparatus in the preferred form -in brief isvas follows:

Gaseous fuel is conducted to the burner 44 and the flame from theburner contacts with the heat deflectors 34 and 37 `of the heating elements and gradually passes upv and out through the apertures 48 formed in the' heating element 29 and asbestos 30 .into the chamber 35, and thence into the room or other enclosure in which the heating apparatus is placed. The apertures 40 formed in the heating element 36 being graduated or varied in size permitting vmore or less airto be admitted between the heating elements and as the gas 'pressure is reduced or increased the flow of air is increased or decreased in prop-ortion through the medium of the graduated openings thereby'automatically mixing the air and gas in proper proportions for properv combustion under different pressures.

The heating elements become intensely heated through 'the medium of the heat deflectors and as they are made of porous porcelain or similar material they are intensely heated diffusing, retaining and radiatingjintense heat into the room in which the heating apparatus is placed thereby economizing in the use of fuel as considerable more heat is produced because of the use of porous heating elements.

As the porcelain heating elements be-.

come intensely heated it is necessary that the same should be of a porous nature to provide for expansion and contraction thereof without cracking or breaking.

Attention is called to the fact that when the heating elements are heated by the burner Athat the same is transmittedto the fire clay walls Vand absorbed, thereby retaining the heat for longer periods of time because of the use of the fire' clay material (or the like) in the construction of the heating apparatusV in combination '.With

metal. c y

In the modification shown in Figs. 7 and 8 attention is called to the fact that the heat deflectors 34 and 37 are not shown on the heating elements. It is preferable, however, to use said heat delectors 34 and 37 as shown in'F ig. 3 as more eiciency and radiation is obtained in producing heatV from a given amount of fuel;

It is not -intended to limit the application oruse of my invention to a stove as the invention shown therein and described can be readily adapted for use without deviating from the principle of my invention and applied to other heating appliances such as furnaces or the like.

I claim:

1.
